    Alcubierre Upscale (a Neil_W design)

    Dang, almost 2 months since I updated things here!!! Most of that time was spent on my L3 project but I did do a little bit on this build. Did some painting. This is the hard part for me. The design comes easy, picking the colors not so much. Thought I would try silver and red. Nose cone...

    A Rabbi "Weighs-In" On Covid-19 . . .

    Yes but the people that go to church are more likely to be in a high risk group. Higher percentage of older people in church then at a "Rock" concert.

    A Rabbi "Weighs-In" On Covid-19 . . .

    Sitting in a crowded church is probably the most effective way of spreading this virus.

    Question on fineness ratio

    I have a bunch of 5.5 inch plastic nosecones in the garage. One with fins and/or a ring fin will happen when I can get to it.. Probably rear ejection.

    Question on fineness ratio

    Even if they meet all of the very specific rules for an L3 attempt? Not that I would do that. My L3 design is a very basic 4FNC. But this looks like a loophole to me..... The fineness of a rocket can show its susceptibility of an airframe to bend in a side wind. I wouldnt think most nosecones...

    Question on fineness ratio

    Not if you put fins on the nosecone. Doesnt say it has to have a body tube.

    Question on fineness ratio

    That might have been my bad. I was looking at the NAR rules and the Tripoli President popped up and Tripoli got pulled into it. My bad.......

    Question on fineness ratio

    If the fineness ratio is for the whole rocket then an "Odd Roc" could still sneak through like I mentioned above with a 5.5 Von Karmen nosecone and no airframe. What prompted my question is if the fineness ratio did not include the nose cone it would insure that odd rocs couldnt sneak in. With...

    Question on fineness ratio

    So I could take a 4 inch diameter 5.5 von Karman nose cone, stick in a motor mount and fins an it would qualify under Tripoli rules with a fineness ratio of 5.5.

    Question on fineness ratio

    When calculating the fineness ratio do you include the nosecone? Case in point. An 8 foot tall rocket with a 6 foot tall, 6 inch diameter body tube and a 2 foot nosecone. Is the fineness ratio 12 or is it 16?

    Keep It Simple,Stupid. My Level 3 build

    So, more progress. Sanded the lower section and fins then did a thin layer of epoxy across the lower airframe and fins. Did a bit more sanding after that dried and 2 coats of Duplicolor clear coat. Mounted the 2 1515 rail buttons, the lower screwed into the aft centering ring (mental note. Next...
